Hydrogen iodide, HI, decomposes at moderate temperatures according to the equation 2HI(9) - H2 (g) + L (g) The amount ofI, in the reaction mixture can be determined from the intensity of the violet color of I,; the more intense the color, the more I, in the reaction vessel. When 3.91 mol HI was placed in a 5.00-L vessel at a certain temperature, the equilibrium mixture was found to contain 0.431 mol I2. What is the value ofK, for the decomposition of HI at this temperature? K. =
